Application filed December a0, 1908.

Specification of Letters Patent.

Serial No. 470,038.

To all whom it. may concern:

Be it known that I, GEORGE SPALDING, of Stockton, in the county of San Joaquin, State of California, have invented acertain new and useful Improvements in Steering- Gear for Tilling-Machines, of which the following is a specification.

This invention relates to certainnew and usefulimprovements in tilling machines.

The invention has for-its object the proof the machine to conform to the. contour of the ground and control thewidth of the I and the character of the work to be perforr'ned.

. A. further object is to provide improved steering" means which will not be affected,

justments of height, width, orotherwise, of the machine, or its carrying frame.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying l is a top plan view of a tilling- Inac ine embodying my invention. Fig; 2' is a detail front view of the steering wheel, parts being shown in section.

Referring to the drawing, designates the frame formed with two members 11, 12, the former being arranged transversely to the line-of draft, and thelatter extending rearwardly from one end of arm 11 to form the backbone. Said backbone is inclined downwardly and deflected laterally or transversely to the line of draft, but I do not desire to limit myself as form of frame; The section 13 is provided with a vertical boss 22 arranged to receive a shaft 23 the lower end of which is bent to form an axle for the forward furrow wheel-2 l which is also the steering wheel.

A steering lever .25 is provided :having at one end a split sleeve 26 embracing the protruding end of the stcering'shaft 22, the free end of said lever arranged to engage arack 27'. Saidv split sleeve is tightened-by means of a bolt, 28, whereby the osition of said sleeve uponl shaft 22 may The adjust ble section 13 is provided with a segmental rack 30 to which is pivoted one end of a hand lever 31 provided'vlsgith to any particular I whlle I have illustratedand described my xtatably mounted in said otally connected at one end to lever .31 is link or bar 33, the lower end of which engages-a lug 34. carried by a collar35 loosely mounted on shaft 23, 'a second collar 36 provided with a set screw 37 to engage said shaft, being arrangedabove collar 35 to revent displacement of the latter. Said ink 33 is provided with a series of holes whereby the connection with the lever-j3l may be adjusted.- The'lower end of link '33 is supported bya flattened formed on the bearing sleeve-37 of wheel 24. The collar 35. also rests upon said table. By this arrangement the link 33 sustains the weight of the 'contiguous'side of the frame,

- and said side is raised or lowered, by manipulating lever 31, without interfering with the steering functions of wheel 24. The

opposite side of the frame is provided withan arm 40 carrying the land wheel ll and connected with the lever 42 by means of a link 43. By this arrangement the contiguous side of the lowered.

In practice, the frame is raised or lowered to conform to the work, by means of levers 31 and42, and after the desired adjustment has been secured the split sleeve 26 is placed in the proper position upon the steering shaft, to conform to said adjustment. In operation, the machine is guided by lever 25 which turns the shaft 22 and wheel-24, saidlever. acting as a tiller handle. end of link'or bar 33 rides upon the table 36, which latter is large enough to permit the wheel 24: to turn and yet sustain the end of said link, thus supporting the weight of the frame at all times. i

It is obvious from the foregoing that improved steering mechanism in connection with an implement of the tilling machine type, it is not. tions, as it is quite apparent that it is equally applicable to various other forms of mac ines. v
